2 Claims.

This invention relates to means for facilitating the addition, shiftingor removal of sheets bound in a loose leaf volume andhas for its objectthe provision of a. new and improved device of this yp V p 7 An objectof this invention is to provide a new and improved loose leaf binderwhich will cooperate with a sheet shiftingand changing member to permittheraddition, shifting, or removal of sheets with the maximum facilityand minimum of error.

.The above as well as other objects are each attained by providing theloose leaf binder and the sheets which are adapted to be placed therein5 with one or more apertures and providing a base member with one ormore prongs adapted to be receivedin said apertures, the said prongsbeing formed oftwo separable elements which inone position form acontinuous guide for the said sheets and in another position permit theposi-' tioning of the said binder prong elements. One of the manypossible embodiments of my inventive concept is'shown in theaccompanying drawings and will herein be more particularly described forthe purpose of illustrating my invention.

upon the said separable In the drawings Figure 1 isa top view of mynovel unit in operative position upon a support. Figure 2 is an enlargedperspective view of my novel binder in the open position, a portionbebetween the ends being broken away to permit the showing of theelements on an enlarged scale. The portion broken away is merely arepetition of the elements shown.

Figure 3 is a perspective view showing the prong carrying or sheet guidemember of my novel combination. The full lines show the V prongs intheir closed position when the prongs are adapted to form a continuousguide for the leaves or sheets and the dot and dash lines show theprongs in the open position when the binder may be positioned on orremoved from the prongs and when leaves may be added, shifted orremoved.

Figure 4 is an enlarged perspective view of a fragment constituting oneof the/ends of my novel unit, the remainder of the unit having beenbroken away to permit the showing on the enlarged scale. The portionbroken away merely constitutes a repetition of the elements hereinshown. This view also illustrates some of the different positions of therespective members and elements of the unit. The full lines show the 55prongs in the open position and the binder just 1933, Serial No. 684,508

after it has been positioned upon the prong elements adapted-to receiveit. The dot and dash lines show one of the binder elements after it hasbeen removed to permit free movement of the leaves and the prongs in theclosed or active position.

Referring more particularly to the drawings wherein similar referencenumerals denote similar parts reference numeral I denotes my novel unitconsisting of a binder member 2 and a sheet guide member 3 which areusually positioned upon a base, support or table T.

The binder member 2 consists of a pair of parallel binding slats 4 and 5each of which carries a plurality of sheet carrying posts 6 each ofwhich terminates in a conical head I which is adapted to be received inan aperture 8 suitably formed and positioned in the slat elements 4 or5.. This structure causes the slats to be at a fixed distance from eachother no matter how;, :many sheets are carried therein. The lower slatelement 5 has attached'thereto near each of the ends thereof a lockingpost 9 which terminates in a locking neck I0 surmounted by a head IIwhich is adapted to be received or extendthrough an; aperture I2suitably formed and positioned on the upper slat 4. The upper slat 4 haspivotally mounted thereon the channeled locking lever I3 which has thelocking slot I4 suitably formed and positioned to receive'therein thelocking neck I0, for locking the two slat members together. The slatmembers 4 and 5 have further formed therein a plurality of spacedregistering prong receiving apertures I5 which adapt the binder forbeing positioned upon the elements 25 of the prong unit 3. The covers I6carried by the binder unit 2 have each formed thereinthe plurality ofapertures I'I'suitably positioned to permit the posts Band 9 to extendtherethrough' and to register with the apertures I5 as may benecessarywhen. the covers are properly positioned in the binder. 7 The leaves I8carried by the binder unit 2 have formed and suitably positioned thereinthe apertures I9 which cooperate withthe post 6 or 6 and 9 to bind thesheets in place and which register 'with the apertures I5 or I! as maybe necessary. For the purpose of uniformity I prefer to space myapertures 8, I2, I5, I1 and I9 and the posts 6 and 9 so that they areequidistant center to center. The sheet guide member 3 consists of abase ele-" mnt20 and the guide and positioning posts or arches 24. v

The base element 20 has positioned thereon along the front edge thereofthe rail 2I which center.

has attached thereto the prong elements 25. The base element 26 hashingedly attached thereto along the rear edge thereof the rail 22 whichcarries the element 26 of each arch 24. The base element 26 has furtherattached thereto the resilient rear rail retaining elements 23. The baseelement 20 has further formed therein the apertures 29 through which mayextend the screws 36 (see Figures 1 and 4) which serve to attach themember 3 to the table T.

It is to be noted that the prong elements 25 and 26 are so formed thattogether they combine to form the U-shaped arch member 24 which in theclosed position (shown by the full lines in Figure 3 and the dot anddash lines in Figure 4) has two substantially straight sides connectedby a curved element 28 and which in the open position (shown by the dotand dash lines in Figure 3 and the full lines in Figure 4) is composedof the element 26, having the straight portion 2'! and the curvedportion 28, and the straight prong element 25. As clearly shown inFigure 4, the straight prong element 25 must be longer than the totalWidth or thickness of the binder 2 and its contents. The straight wallsand curved connecting portion of the arch 24 serve to facilitate themovement of the cover 16 and the leaves l8 about the arches or guides 24in the removal, shifting or the addition of leaves to the binder 2. Forthe sake of uniformity the prongs 24 have been so spaced as to beequidistant center to Although the manner of using my novel de vice isbelieved to be clear from the foregoing disclosure, yet to obviate anypossibility of a misunderstanding the following detailed description ishere given. Although it is not necessary to attach the sheet guidemember 3 to the table T yet since by making such attachment the unit ismade more stable we will-therefore assume that the sheet guide member 3has been assembled and has been fastened down to a suitable table T bythe screws 36 extending through the aper tures 29. Let us further assumethat we start with the elements 25 and 26 of the arches 24 in theposition shown by the full lines in Figure 3.

Let it be further assumed that we desire to replace several leavescarried by the binder 2. To add, remove, shift or replace leaves weproceed as follows:

The prong elements 26 are moved to open position (shown by the dot anddash lines in Figure 3 and the full lines in Figure 4). The binder 2 andthe leaves which it carries are then placed upon the sheet guide member3 to take the position shown by the full lines in Figure 4 so that thestraight prong elements 25 extend through the registering apertures l5,l7 and 19. The locking levers H are then manipulated so as to unlock theslat 4. The slat 4 is then moved upwardly away from the ensemble asshown by the dot and dash lines in Figure 4. The prong elements 2B arethen swung back to the'closed position shown by the dot and dash linesin Figure 4 and the full lines in Figure 3. When in this position theprong elements 25 and 25 combine to form a continuous guide element forthe leaves which can now be moved to uncover the leaves at any point inthe bound volume. When certain of the leaves have been shifted from theelements 25 to the elements 26 to uncover those desired,

such, for instance, as shown in Figure 1, the prong elements 26 areagain swung outwardly to the open position and the new leaves 18 placedin position upon the posts 6 and the prong elements 25, or the oldleaves are removed and replaced by new leaves or the leaves which are tobe shifted are removed preparatory to shifting. After the sheets havebeen added or removed as may have been necessary the prong elements 26are again swung back to the closed position (shown by the full lines inFigure 3 and the dot and dash lines in Figure 4) and the leaves !8 areswung back to the position shown in Figure 4. If it is desired to shiftthe leaves which have been removed to another position in the binder,the leaves remaining upon the guide means are shifted to the desiredpoint where the insertion is to be made, the prong elements 26 arethrown to the open position and the leaves being shifted are inserted.)All of the above operations can be repeated any number'of times desired.When the above operations have been completed the prong elements 26 arethen swung back to the open position and the slat 4 is replaced andlocked in the position shown by the full lines in Figure 4. The binderand its contents are now removed from the guide member 3 for usewherever desired.

It is obvious that the method herein outlined may be used not only forthe transferring and adding and removing of sheets wherever desired, butalso for the assembling of sheets uponthe binder element 2. I

It is to be understood that the above disclosure is for the purpose ofillustration only and not for the purpose of limitation since manychanges may be made in the structure herein shown without departing fromthe spirit of my invention. It is for this reason that it is my desirethat the claims which are hereunto appended for the purpose of definingmy invention should be limited only by the prior art I claim:

1. A loose leaf binder consisting of a pair of slats each having aplural number of leaf binding posts positioned thereon and a pluralnum-' ber of apertures formed therein and positioned for receiving eachof said binding posts, a locking post mounted on one of said slats and alocking lever positioned on theother of said slats for cooperativeengagement with the said locking post for locking the said slatstogether, each of said slats having further formed therein one or moremounting apertures so positioned that the apertures of one slat registerwith the apertures of the other slat. V

2. A loose leaf binder consisting of a pairof slats each having aplurality of cone headed leaf binding posts attached thereto and apluralityof apertures suitably formed and positioned therein.

for receiving the said cone shaped heads of the said binding posts, alocking post positioned on one of said slats near each of the endsthereof and a locking lever suitably positioned on the other of saidslats near each of the ends thereof for cooperative engagement with each'of said locking posts to lock the said slats together, each of thesaidslats having further formed therein a plural number of mountingapertures so posi- "tioned that the apertures'of one slat register withthe apertures 01 the other slat.
